kube-prometheus-stack Helm Chart
Automate the deployment and configuration of the Prometheus monitoring stack in Kubernetes clusters using Minimus images. The chart deploys Prometheus, Alertmanager, Grafana, node-exporter, kube-state-metrics, and the Prometheus Operator.
Prerequisites
- A subscription to the Minimus images included in the chart
- A running Kubernetes cluster (v1.25 or higher is recommended)
kubectl installed and configured- Helm v3.8 or higher for OCI support (Installation instructions)
- Cluster Admin privileges
Note: kube-prometheus-stack deploys CRDs (Custom Resource Definitions) for Prometheus, Alertmanager, ServiceMonitors, and related resources. Ensure your cluster allows CRD creation.
Try It Out
In this example we will deploy the kube-prometheus-stack on a Kubernetes cluster using the Minimus Helm chart. This provides full cluster monitoring with Prometheus, Grafana dashboards, and alerting via Alertmanager.
Step 1: Start Cluster
If you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. Deployment instructions
Step 2: Create Namespace
Create a namespace:
kubectl create ns monitoring
Step 3: Save Values File Locally
Go to the Values tab and save a copy of it locally.
Step 4: Deploy the Helm Chart
Deploy the Minimus Helm chart with the values.yaml file you saved in the previous step:
helm install my-kube-prometheus-stack oci://helm.mini.dev/kube-prometheus-stack \
--version 83.4.0 \
-f values.yaml \
-n monitoring \
--wait
Step 5: Verify the Stack is Running
Confirm the chart deployed successfully and all components started:
kubectl get pods -n monitoring
You should see output similar to:
NAME READY STATUS RESTARTS AGE
my-kube-prometheus-stack-grafana-xxxxx 3/3 Running 0 2m
my-kube-prometheus-stack-kube-state-metrics-xxxxx 1/1 Running 0 2m
my-kube-prometheus-stack-operator-xxxxx 1/1 Running 0 2m
my-kube-prometheus-stack-prometheus-node-exporter-xxxxx 1/1 Running 0 2m
alertmanager-my-kube-prometheus-stack-alertmanager-0 2/2 Running 0 2m
prometheus-my-kube-prometheus-stack-prometheus-0 2/2 Running 0 2m
Step 6: Access Grafana UI
Port-forward to the Grafana service to access the dashboards:
kubectl port-forward svc/my-kube-prometheus-stack-grafana -n monitoring 3000:80
Access Grafana at http://localhost:3000. The default username is admin and you can retrieve the password with:
kubectl -n monitoring get secret my-kube-prometheus-stack-grafana -o jsonpath="{.data.admin-password}" | base64 -d
Step 7: Access Prometheus UI
Port-forward to the Prometheus service:
kubectl port-forward svc/my-kube-prometheus-stack-prometheus -n monitoring 9090:9090
Access Prometheus at http://localhost:9090.
Step 8: Clean Up
Uninstall the chart and delete the namespace to remove all resources:
helm uninstall my-kube-prometheus-stack -n monitoring
kubectl delete namespace monitoring
